SMTP Mailing Queue

Опис

This plugin adds emails to a mailing queue instead of sending immediately. This speeds up sending forms for the website visitor and lowers the server load.
Emails are stored as files which are deleted after emails are sent.

You can send all outgoing emails via an SMTP server or (the WordPress standard) PHP function mail, and either use wp_cron or a cronjob (if your server/hoster supports this) to process the queue.

Plugin requires PHP 5.4 or above.

Tools:

You can send test mails to test your setup.

You can process the mailing queue manually instead of waiting for cronjob.

You can display the mailing queue in the backend to see emails that will be sent with next processing.

Exactly what I needed for my volunteer portal. We regularly email our 1500 users and my email servers yell at me every time. This is batching nicely and works perfectly with the Email Users plugin. Also, I left all the SMTP settings blank and it passes everything through to my two other plugins (WP Better Emails and SAR Friendly SMTP) beautifully.
